Religious and metaphysical subjects have been a continuing source of fascination for Rautavaara. The key to his belief lies not in a specific doctrine, but in the words of the German philosopher Friedrich Schleiermacher that 'true religion is sense and taste for the infinite'. Another theme within Rautavaara's work stems from his belief in the existence of angels - but for him, the angel is not golden and cherubic and a rather more menacing figure as described by the German poet Rilke.
